thank you very much for helping-out a newbie like me, really appreciate it sir! i really don't know much about engines/car components but very much eager to learn about it.

questions:
1. what if the white smoke does not disappear even after running the car for more than 10 minutes?

2. compression testing would determine whether the engine requires a top or general overhaul?

3. white smoke only comes out of the tailpipe and not on the cylinder head/engine, so does this mean that my engine is running ok?

4. do i still need to buy products that stops engine leaks (STP products)?

i'm located in san juan.

i'll pm you contact nos. of shops that may be of help to you asap.where are you based, btw?
